Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. Although any methods and materials similar or equivalent to those described herein can be used in the practice or testing various embodiments, the preferred methods and materials are now described.

While the description of the preferred embodiments hereinbelow is with reference to an off-grid location lighting fixture for railroad applications, it will become evident to those skilled in the art that the embodiments are not limited thereto, but are also adaptable for employing the off-grid location lighting fixture for various other applications such as, for example, illuminating road intersections, industrial yards, and parking lots.

Referring to FIGS. 1 to 5 an off-grid location lighting fixture 100 according to a preferred embodiment is provided. The off-grid location lighting fixture 100 comprises base 102 having a bottom portion of pole 104 mounted thereto. Preferably, the base 102 is adapted to be placed adjacent to a railway envelope 12 with minimum site disturbance, as will be described hereinbelow. Solar panel 106 is mounted to a top end portion of the pole 104. LED Light 108, preferably, mounted to an upper portion of the pole 104 via arm 110, is adapted to light an area at a predetermined location on ground adjacent to the light fixture 100 such as, for example, a section of a railway line 12, as indicated by the dashed lines in FIG. 1. Electrical boxes 112 are mounted, for example, to the base 102 for providing a weather-proof enclosure for one or more batteries and control circuitry contained therein. It is noted that, while two electrical boxes 112 are shown in the Figures, the embodiments are not limited thereto, but only one or more than two electrical boxes may be employed. The battery is connected to the solar panel 106 and the LED light 106 via electrical wiring which is, preferably, disposed inside the pole 104 and the arm 110. The battery stores the electrical energy received from the solar panel 106 during daytime and provides the same to the LED light 108 during nighttime. The control circuitry is connected to the solar panel 106, the LED light 108, and the battery. The control circuitry controls the storage of the electrical energy and the provision of the same to the LED light 108. Preferably, the solar panel 106, the LED light 108, the battery, and the control circuitry are adapted such that the lighting fixture 100 is operable as a self-contained unit absent any service connections.

Preferably, the pole 104 is mounted to the base 102 such that the same is pivotally movable about pivot 114 between a first position with the pole 104 being oriented substantially horizontal and a second position with the pole 104 being oriented substantially vertical, as indicated by the block arrow in FIG. 2. The pivotal movement of the pole 104 with respect to the base 102 substantially facilitates installation and maintenance of the lighting fixture 100 by enabling work on the solar panel 106 and the LED light 108 on the ground, thus obviating work at height.

Further preferably, the lighting fixture 100 is adapted such that the LED light 108 illuminates an area of the railway 12 adjacent to the lighting fixture 100 in the direction of the pivotal axis 114, as illustrated in FIGS. 1 and 2, thus enabling placing of the lighting fixture 100 such that in the horizontal position the pole 104 is oriented substantially parallel to the railway track 12 which substantially facilitates installation and maintenance of the lighting fixture 100 without substantially disturbing railway traffic.

Further preferably, the base 102 is adapted for being mounted to a screw pile 118, as illustrated in FIG. 4, thus enabling easy installation without significant site disturbance by simply drilling the screw pile 118 into ground 10 and mounting base plate 102A thereto. Alternatively, the base plate 102A may be mounted to a foundation.

In an example implementation for providing location lighting for railway switches, the lighting fixture 100 comprises a pole 104 made of commercially available aluminum tubing having a length H4 of approximately 20′ and a diameter of 3″. The base 102 comprises a flat 10″ by 10″ (WB) base plate 102A made of aluminum having welded thereto vertical base extension 102B, made of a commercially available U-shaped aluminum profile having length H3 of approximately 58″ and a 6″ by 10″ cross section. The bottom portion of the pole 104 is accommodated inside the base extension 102B and secured thereto using pins or bolts 114 and 116 accommodated in respective apertures disposed in the pole 104 and the base extension 102B. Using pins or bolts 114 and 116 enables pivotally movable mounting of the pole 104 to the base extension 102B about bolt or pin 114. For example, during installation the pole 104 is first mounted to the base extension 102B via bolt or pin 114 having a substantially horizontal orientation and then erected into the vertical position and secured via bolt or pin 116. The base plate 102A is adapted for being mounted to a top of a commercially available screw pile 118 using, for example, screw fasteners.

Commercially available LED light 108 is mounted to the pole 104 via arm 110 made of commercially available 2″ by 2″ aluminum tubing having a length LA of 2′ at height H2 of approximately 14′ above ground.

Commercially available solar panel 106 having length Lsp of approximately 5.5′ and width Wsp of 4′ is mounted to the top of the pole 104 at angle a of approximately 45° to the horizontal, as illustrated in FIG. 4, giving the lighting fixture 100 a total height H1 of approximately 21.5′. The solar panel 106 is mounted to the pole 104 using conventional fasteners, preferably, such that during installation the solar panel can be rotated with respect to the pole 104 in order for the solar panel 106 to be oriented such that capture of sunlight is maximized.

As is evident to one skilled in the art, the lighting fixture 100 may be provided having various dimensions and can be made of different materials such as, for example, steel or composite materials, depending on design preferences.

The LED light 108, the solar panel 106 and the battery or batteries are chosen such that the LED light 108 provides sufficient lighting while the solar panel 106 and the batteries provide sufficient electrical power for a sufficient length of time.

The control circuitry comprises, for example, a processor for controlling the capture and provision of electrical power. The provision of electrical power to the LED light 108 can be controlled in different ways. For example, using a timer electrical energy is provided between predetermined hours of the day. Alternatively, a light sensor is employed to provide a signal when the ambient light is below a predetermined threshold. Further alternatively, a motion sensor is employed to provide a signal when there is a train in proximity of the lighting fixture 100.

Optionally, the lighting fixture 100 comprises a wireless network module such as, for example, a cellular modem, for wireless data transmission of, for example, a camera video stream from a camera mounted to the lighting fixture 100 or other sensor data such as data from a contact sensor disposed in the railway switch for providing live sampled switch indications to the control system of the railroad. The solar panel 106 and the battery are then adapted to be capable to also power the wireless network module, the camera and/or other sensors.

The pole might further include a handle, or a powered winch apparatus or the like, to permit simplified raising and lowered of the pole through its pivotal range of movement. Embodiments with or without such a handle or winch apparatus are all contemplated within the scope hereof.

It will be apparent to those of skill in the art that by routine modification one or more embodiments can be optimized for use in a wide range of conditions and application. It will also be obvious to those of skill in the art that there are various ways and designs with which to produce the apparatus and methods of the present disclosure. The illustrated embodiments are therefore not intended to limit the scope of the invention, but to provide examples of the apparatus and method to enable those of skill in the art to appreciate the inventive concept.

Those skilled in the art will recognize that many more modifications besides those already described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the scope of the appended claims. Moreover, in interpreting both the specification and the claims, all terms should be interpreted in the broadest possible manner consistent with the context. The terms “comprises” and “comprising” should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps may be present, or utilized, or combined with other elements, components, or steps not expressly referenced.
